This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,748.

Summary of the Inventive Concept

A novel composition delivery system that utilizes multi-frequency energy sources and real-time feedback control to optimize therapeutic agent delivery, improving treatment efficacy and minimizing side effects.

Background and Problem Solved

Current methods and devices for treating occlusions in the body employ balloon catheters or stents to deliver drugs, but these devices have limitations in terms of prolonged delivery and real-time monitoring. The present inventive concept addresses these limitations by introducing a multi-frequency energy source and real-time feedback control, enabling more efficient and targeted composition delivery.

Detailed Description of the Inventive Concept

The enhanced composition delivery system comprises a multi-frequency energy source, a composition delivery element, and a feedback control system. The multi-frequency energy source can selectively deliver radiofrequency, ultrasound, or laser energy to a body region, allowing for more flexible and effective treatment. The composition delivery element is adapted to receive the energy and release a therapeutic agent in response. The feedback control system adjusts the energy output based on real-time monitoring of the body region, ensuring optimal delivery and minimizing side effects. The system can be used to treat various conditions, including occlusions in blood vessels or grafts, tumors, and other diseases.

Novelty and Inventive Step

The novelty of the present inventive concept lies in the combination of a multi-frequency energy source and real-time feedback control, which enables more efficient and targeted composition delivery. The inventive step is the integration of these components to create a system that can adapt to changing conditions in the body region and optimize treatment efficacy.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of energy sources, such as microwave or electrical energy, or incorporating additional sensors to monitor the body region. Variations could also include using the system to deliver multiple therapeutic agents in a predetermined sequence and concentration, or integrating the system with other medical devices, such as imaging equipment or surgical tools.

Potential Commercial Applications and Market

The enhanced composition delivery system has significant commercial potential in the medical device industry, particularly in the areas of cardiology, oncology, and radiology. The system's ability to optimize treatment efficacy and minimize side effects could lead to improved patient outcomes and reduced healthcare costs. The target market includes hospitals, clinics, and medical research institutions.
